Struct rustc_span::CharPos

pub struct CharPos(pub usize);

A character offset.

Because of multibyte UTF-8 characters, a byte offset is not equivalent to a character offset. The SourceMap will convert BytePos values to CharPos values as necessary.

Tuple Fields

0: usize

Trait Implementations

impl Add for CharPos

type Output = CharPos

The resulting type after applying the + operator.

fn add(self, rhs: CharPos) -> CharPos

Performs the + operation.

impl Clone for CharPos

fn clone(&self) -> CharPos

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CharPos

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Ord for CharPos

fn cmp(&self, other: &CharPos) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for CharPos

fn eq(&self, other: &CharPos) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for CharPos

fn partial_cmp(&self, other: &CharPos) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Pos for CharPos

fn from_usize(n: usize) -> CharPos

fn to_usize(&self) -> usize

fn from_u32(n: u32) -> CharPos

fn to_u32(&self) -> u32

impl Sub for CharPos

type Output = CharPos

The resulting type after applying the - operator.

fn sub(self, rhs: CharPos) -> CharPos

Performs the - operation.

impl Copy for CharPos

impl Eq for CharPos

impl StructuralPartialEq for CharPos

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
